[PHP] Ora_Parse failed

[Matt Hillebrand]

I have an Oracle 8 problem. Unfortunately, I can't use the OCI functions and must use 
the ORA functions. The code below looks fine to me. It will return *almost* all of the 
rows, but then the script just dies with no warnings or errors, even though I have 
called error_reporting(E_ALL). I do get the following error message in an Apache error 
log:
 
Ora_Parse failed (ORA-00936: missing expression -- while processing OCI function 
OPARSE).

Here's my code:

<?
   $query = "select $columns from $table where $where_clauses";
   ora_parse($cursor, $query) or die("<br>ora_parse() failed: ".ora_error());
   ora_exec($cursor) or die("<br>ora_exec() failed: ".ora_error());

   print '<br><br><a name=results><table border=1>';
   $rowcount = 0;

   while(ora_fetch($cursor)) {
      print '<tr>';
      for($i=0; $i<sizeof($columns); $i++) {
         $cell_data = ora_getcolumn($cursor, $i);
         if($cell_data === false)
            die("ora_getcolumn() failed: ".ora_error());
         print "<td>$cell_data</td>";
      }
      print "</tr>\n";
   }

   print '</table>';
?>

Thanks for any advice.
